Abstract:

Two experiments were conducted in which the CFF of the occluded and non-occluded eye was determined before and after one week of monocular deprivation darkness. No significant changes occurred in the occluded eye, but a significant increase in the CFF of the non-occluded eye was present, an improvement which occurred regardless of whether the dominant or non-dominant eye was visually deprived. In a third experiment, in which the CFF of the non-occluded eye was measured at intervals of 0, 13, 1, 2, 3, 5, and 7 days of monocular deprivation, a negatively accelerating improvement in performance, as a function of duration, was observed. Furthermore, some evidence was obtained which indicated that this interocular effect was still present, to a noticable degree, one week after the removal of the occluding eye patch. The findings of this series of experiments were related to the denervation supersensitivity phenomenon of Cannon and Rosenblueth 1949 and to Sharplesss 1964 concept of disuse of neural pathways.
